Hydrogeological Characterization and Approach to a Conceptual Model of the Aquifer of the Cuvette Basin, Republic of Congo

The continuous aquifers of the Congolese Cuvette basin constitute seat significant water tables reversibly supplying Congo River as well they drain. Consisting mainly sandy-clayey-sandstone formations, these contain groundwater which is main source drinking supply for communities in this sector departments and Cuvette-Ouest. need being more acute, have been subjected to drilling operations order populations. information obtained from data made it possible obtain relating lithology, hydrogeological parameters on depth lateral variations table. purpose present work contribute characterization aquifer Cuvette-Ouest via analysis technical sheets drillings carried out by ASPERBRAS Company, collected at Ministry Major Works territory planning. This was using Visual MODFLOW Flex 2015.1 software coupled with Surfer 10 Rock 17 software. interpretation shows that aquifer, whose constitution essentially up sands, clayey sands clay, continuous, porous free. composition gives a heterogeneous character. In addition, piezometric map produced indicate direction flows turned be west east towards lowest areas occupied valleys rivers rivers. conceptual model deceases considerably Cuvette.
